Holybro Pixhawk 4 error. Says "RC16 minimum value greater than trim"

I configured PX4 with MissionPlanner and it worked just fine and then at the field connected with QGroundControl. It kept throwing the error “RC16 minimum value greater than trim”. I tried everything from flashing new firmware to calibrating the radio and changing the radio but it is stuck giving that error. I checked with some older stable firmware too like 3.6.9 and 3.6.11 to 4.0.0 and 4.0.1. The error does not seem to go away. Please help asap.

Just go into the full parameter list and set the minimum value to less than the trim value.
Typically min would be 1000, trim would be 1500, max would be 2000
I think there was some check to see if those values had shifted from defaults, so if the problem persists just set min to 999 or 1001
